hell yeah!! i'm doing the exact same deal with my parents, only i've only started doing more minor stuff. my dad has gone as far as to say i cannot even take off the mudflaps.. so you might think im totally screwed, but the best thing is he's VERY VERY VERY stupid about cars, right now i have a shortshifter, and intake on, and thats it, but a header is going to be on soon so i'm not so sure if that will pass.. also i have coilovers in the mail, ill drop it an inch for standard daily driving, (he wont notice lol) and for moutain runs slam it down farther. i'm just glad he doesnt know a damn thing about cars.
